Class : Class 9
just because we can see the whole moon during a full moon dosen't mean that on that day there will be the greatest tides as the moon dosen't cut itself into half on 1st and 3rd quarter. So, the answer must depend on the distance of the moon from the earth as the gravitational pull of the moon will have more effect when it is closer to earth and will raise bigger tides. The moon is closest to earth at phases D and H. So, clearly the answer should be A

Ans 4:

Class : Class 6
I do with Harsh Sobti.

Ans 5:

Class : Class 7

Ans 6:

Class : Class 10

Ans 7:

Class : Class 10
It is (A)

Ans 8:

Class : Class 8
It is B. Don't go on the picture. Full and new moon are always closer to Earth.

Ans 9:

Class : Class 7

Ans 10:

Class : Class 9
Ohh yeah,, it is A

Ans 11:

Class : Class 6
The answer is (a) because when the full moon and new moon are there then the sun, earth and moon are aligned and the sun is also pulling at the sea forming big tides.

Ans 12:

Class : Class 9

Ans 13:

Class : Class 9
Answer is B only.

Ans 14:

Class : Class 9
It is a fact that the highest tides occur when the moon is full or new. In the diagram, the positions F and J are the full moons and new moons, so the correct answer should be B

Ans 15:

Class : Class 10
Phases D and H are suitable. Or not?😄

Ans 16:

Class : Class 7
Class:It should be A

Ans 17:

Class : Class 5

Ans 18:

Class : Class 10
Look at the diagram.........the faces of moon closest to the earth are D and H, hence the suitable solution is A

Ans 19:

Class : Class 7
B

Ans 20:

Class : Class 9
Bbbbbbb!

Ans 21:

Class : Class 5

D. At the equator and at 60 degree north and south pole

Ans 6:

Class : Class 6
The answer is D as low pressure exists in both equator and 60 degree north and south.

Ans 7:

Class : Class 9
D is answer as low pressure exists both in equator and 60° lattitude

Ans 8:

Class : Class 6
yes, the correct answer is D since there are two belts of low pressure on the earth. on the equator (due to high temperature) and between the two belts of high pressure (60 degrees North and South. ). A cannot be the correct answer.

Ans 9:

Class : Class 7

Ans 29:

Class : Class 9
Both the science and geography textbooks of NCERT state that there is low pressure at 60 degree North and South also. So, the answer is D.

Ans 30:

It should be D, as per the SOF Foundation Text.
